Abstract

The casing drilling technology is a rising drilling technology.Jilin Oilfield researched the technology and matching tools of casing drilling based on the trait of casing drilling and the fundamental of technology and installation indigenous,and has done site test in 11 wells in the Taobao,Fuyu and Xinmin region,used the generation bit connecting tripping device,did the open hole log in the main oil layer,completed 1000m casing drilling,and acquired a favorable effect.The results demonstrated that the advanced indigenous casing drilling technology should turn out to be a new drilling technology which could cut the cost,raise the benefit,and had an extensive foreground.
